Natasha Harris, 31, died of a cardiac arrhythmia likely brought on from consuming too much caffeine, the coroner's report stated, according to TVNZ.

She reportedly drank so much of the beverage that many of her teeth rotted, and one of her eight children was born without enamel on his or her teeth.

The woman's partner told the station that she would drink nothing but Coca-Cola and would exhibit withdrawal symptoms if she had to go without it.

"The symptoms Natasha had complained of in the months before her death - describing nausea, vomiting and a racing heart-beat - were indicative of someone who consumes high doses of caffeine." TVNZ reported.

But the coroner, David Crerar, stressed that Coca-Cola should not be blamed for customers who consume an unhealthy amount of products.
